Abstract
Ce filtre est constitué par une enceinte tubulaire 2 d'axe vertical comportant une chambre annulaire 3 ouverte à sa partie inférieure et fermée à sa partie supérieure, et une chambre centrale 4 fermée à sa partie inférieure et ouverte à sa partie supérieure, les chambres annulaire et centrale communiquant par l'intermédiaire d'au moins un élément séparateur 6 comportant des passages en chicane, le fluide pénétrant à la partie inférieure de l'appareil dans la chambre annulaire, passant par les éléments séparateurs dans la chambre centrale, puis sortant de celle-ci à la partie supérieure de l'appareiL L'appareil comporte également un dispositif de nettoyage des éléments séparateurs, fonctionnant en dehors des périodes de filtration.
